Monaco's Royal Twins Prince Jacques and Princess Gabriella Started School Today

Prince George, Princess Charlotte, and Prince Louis might have some competition in the cutest-royal-kids in Europe department.

Today, Monaco's three-year-old royal twins, Prince Jacques and Princess Gabriella, went back to school, and in honor of the occasion, their mother, Her Serene Highness Princess Charlene, posted a few sweet candids of the youngsters on her Instagram account. (Swipe right to see all three images of the children with their backpacks on.)

This summer has proven to be quite busy for the younger members of the House of Grimaldi. At the end of August, Prince Jacques and Princess Gabriella attended Monaco's annual end of summer picnic, both fully decked out in the country's traditional attire.

“[It] was a very, very, very beautiful evening,”one attendee toldPeople. “The children clearly enjoyed themselves with their cousins around them and, the music and food.”

They also reportedly vacationed with their whole family in Tahiti.

Unlike Duchesses Meghan and Kate, whose public communications are run through social media accounts for Kensington Palace, members of the other European royal families often do have personal Instagram profiles. And over the past few months Princess Charlene, who is married to Grace Kelly's son, Prince Albert II, has posted several other photos of her children.

For example, Charlene captioned this pic of the twins kissing a penguin from early September, "Happy Feet ????????."
